Description

WO 2013/083614 PCT/EP2012/074468 1 Syringe carrier Technical Field 5 The invention relates to syringe carrier. Background of the Invention In a conventional medicament delivery device (e.g., an autoinjector), a pre-filled syringe 0 is housed in a carrier which is axially movable to achieve needle penetration in an injection site and, optionally, needle withdrawal. A conventional carrier provides shoulders that are adapted to engage a neck on the syringe and prevent the syringe from disengaging the carrier. Because syringes are generally supplied with rigid needle shields covering the needle and those needle shields have a diameter greater than a 5 diameter between the shoulders, a separate assembly step is required - inserting the syringe in the carrier and then attaching the rigid needle shield to the needle. Accordingly, there is a need for a syringe carrier which does not require this separate assembly step. 20 Summary of the Invention It is an object of the present invention to provide an improved syringe carrier. In an exemplary embodiment, a syringe carrier according to the present invention a 25 body adapted to receive a barrel of a syringe. The body includes a longitudinal slot and a distal end having resilient distal clamps with shoulder sections which are adapted to engage a circumferential gap between the barrel of the syringe and a needle shield covering a needle of the syringe. 30 In an exemplary embodiment, the distal clamps deflect when engaged by the barrel and thereafter return to a non-deflected position to engage the circumferential gap between the barrel of the syringe and the needle shield.

WO 2013/083614 PCT/EP2012/074468 2 In an exemplary embodiment, the body further includes resilient proximal clamps adapted to deflect when engaged by the barrel and thereafter return to a non-deflected position to engage a proximal end of the barrel. 5 In an exemplary embodiment, the longitudinal slot extends over the entire length of the body. In an exemplary embodiment, an annular collar is formed at a proximal end of the body. 0 One or more groove hinges are formed in the body adjacent the collar. When the needle shield engages the distal clamps, the body deflects about the one or more groove hinges, and when the needle shield disengages the distal clamps, the body returns to a non-deflected position and the shoulder sections engage the circumferential gap between the barrel of the syringe and the needle shield. 5 In an exemplary embodiment, the shoulder sections include proximally-facing contoured surfaces to accommodate a proximal portion of a neck of the syringe and distally-facing planar surfaces to abut the needle shield. 20 In an exemplary embodiment, the body includes one or more viewing windows. In an exemplary embodiment, the body includes a retainer element adapted to provide an abutment surface to prevent the syringe from disengaging the syringe carrier in a proximal direction. 25 Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and 30 modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

Detailed Description Generally, and applicable to all exemplary embodiments of the present invention, the 0 syringe 2 comprises a barrel 2.1 and a neck 2.2 which has a smaller diameter than the barrel 2.1. A needle 3 is mounted to the neck 2.2 and a rigid needle shield (RNS) 4 is removably arranged on the needle 3. When coupled to the needle 3, a portion of the RNS may cover a portion of the neck 2.2, leaving a circumferential gap between the barrel 2.1 and the RNS 4. The RNS 4 has a diameter substantially equal to the diameter 5 of the barrel 2.1. Figures 1-4 show a first exemplary embodiment of a syringe carrier 1 according to the present in invention. Figure 1 is a top view of the syringe carrier 1 for supporting a syringe 2. Figure 2 is a lateral view of the syringe carrier of figure 1. Figure 3 is a 20 longitudinal section of the syringe carrier of figure 1 in the section plane A-A. Figure 4 is a perspective view of the syringe carrier of figure 1 without the syringe 2. As shown in Figures 1-4, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 has a cylindrical 25 shape with an internal diameter corresponding to the diameter of the barrel 2.1. The body 1.1 comprises a collar 1.2 at a proximal end dimensioned to allow axial insertion of the syringe 2 into the syringe carrier 1 in a distal direction D. Resilient sections 1.1.1 extend distally from the collar 1.2. Distal ends of the sections 1.1.1 include shoulder sections 1.4 shaped as portions of a circle arranged in a transverse plane with respect 30 to a longitudinal axis of the carrier 1. The shoulder sections include facing surfaces 6. When the sections 1.1.1 are in a non-deflected position, the facing surfaces 6 may abut each other, and the shoulder sections 1.4 form a circular shoulder (because the facing WO 2013/083614 PCT/EP2012/074468 8 surfaces 6 abut each other) adapted to engage the circumferential gap between the barrel 2.1 and the RNS 4. The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe 5 carrier 1 by sliding the syringe 2 in the distal direction D into the syringe carrier 2. When the RNS 4 abuts the shoulder sections 1.4, additional axial force may be applied to cause the arms 1.3 to deflect radially. When the RNS 4 has bypassed the shoulder sections 1.4, the sections 1.1.1 may return to the non-deflected position, and the shoulder sections 1.4 may engage the circumferential gap between the barrel 2.1 and 0 the RNS 4 and prevent the syringe 2 from moving in the distal direction D relative to the syringe carrier 1. In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may be arranged to receive a finger flange 2.3 of the syringe 2. 5 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. 20 In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut outs in the arms 1.3 are substantially contiguous when the arms 1.3 are in the non deflected position (as shown in Figure 1). A projection 1.6 may be formed around each 25 cut-out, and when the sections 1.1.1 are in the non-deflected position, the projections 1.6 may form an outline for the window 5. In another exemplary embodiment, the windows 5 may be formed in the sections 1.1.1. Figures 5-8 show a second exemplary embodiment of a syringe carrier 1 according to 30 the present invention. Figure 6 is a lateral view of the syringe carrier 1 of figure 5. Figure 7 is a longitudinal section of the syringe carrier 1 of figure 5 in the section plane WO 2013/083614 PCT/EP2012/074468 9 A-A. Figure 8 is a perspective view of the syringe carrier of figure 5 without the syringe 2. As shown in Figures 5-8, the syringe carrier 1 comprises an elongate body 1.1 arranged 5 to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 is comprised of two resilient sections 1.1.1 which, when together, have a cylindrical shape with an internal diameter corresponding to the diameter of the barrel 2.1. Distal ends of the sections 1.1.1 of the body 1.1 comprise part of a collar 1.2 dimensioned to allow axial insertion of the syringe 2 into the syringe carrier 1. Resilient arms 1.3 are formed in the 0 body 1.1. Distal ends of the arms 1.3 include shoulder sections 1.4 shaped as portions of a circle arranged in a transverse plane with respect to a longitudinal axis of the carrier 1. The shoulder sections include facing surfaces 6. When the arms 1.3 are in a non deflected position, the facing surfaces 6 may abut the distal ends of the sections 1.1.1 of the body 1.1 to form a circular shoulder adapted to engage the circumferential gap 5 between the barrel 2.1 and the RNS 4. The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 in the distal direction D into the syringe carrier 2. When the RNS 4 abuts proximal ends of the sections 1.1.1, the sections 1.1.1 may deflect 20 radially. When the RNS 4 has bypassed the proximal ends of the section 1.1.1, the sections 1.1.1 may return to the non-deflected position. When the RNS 4 abuts the shoulder sections 1.4, the arms 1.3 may deflect until the RNS 4 bypasses the shoulder sections 1.4. Then, the arms 1.3 may return to the non-deflected position, and the shoulder sections 1.4 and the collar 1.2 may engage the circumferential gap between 25 the barrel 2.1 and the RNS 4 and prevent the syringe 2 from moving in the distal direction D relative to the syringe carrier 1. In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may be arranged to receive a finger flange 2.3 of the syringe 2. The proximal end 1.5 may also include a 30 retainer element 1.7 which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.

WO 2013/083614 PCT/EP2012/074468 10 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. 5 In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut outs in the sections 1.1.1 are substantially contiguous when the sections 1.1.1 are in the non-deflected position (as shown in Figure 5). A projection 1.6 may be formed around 0 each cut-out, and when the sections 1.1.1 are in the non-deflected position, the projections 1.6 may form an outline for the window 5. 5 Figures 9-13 show a third exemplary embodiment of a syringe carrier 1 according to the present invention. Figure 9 is a top view of a third embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 10 is a lateral view of the syringe carrier 1 of figure 9. Figure 11 is a longitudinal section of the syringe carrier 1 of figure 9 in the section plane A-A. Figure 12 is a perspective view of the syringe carrier of figure 9 without the syringe 20 2. Figure 13 is another perspective view of the syringe carrier of figure 9. As shown in Figures 9-13, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 is comprised of two sections 1.1.1 which, when together, have a cylindrical shape with an 25 internal diameter corresponding to the diameter of the barrel 2.1. The sections 1.1.1 may be coupled by a side hinge which allows the section 1.1.1 to rotate relative to each other sufficient to receive the syringe 2. Proximal and distal ends of the sections 1.1.1 include shoulder sections 1.4 shaped as portions of a circle arranged in a transverse plane with respect to a longitudinal axis of the carrier 1. The shoulder sections include 30 facing surfaces 6. When the sections 1.1.1 are in a closed position, the facing surfaces 6 may abut each other so that the shoulder sections 1.4 form circular shoulders adapted to proximally abut a finger flange 2.3 on the syringe 2 and to distally engage the WO 2013/083614 PCT/EP2012/074468 11 circumferential gap between the barrel 2.1 and the RNS 4. The facing surfaces 6 of one section 1 .1.1 may include holes 1.10 and the facing surfaces 6 of the other section 1.1.1 may include pins 1.11 adapted to engage (e.g., frictionally, snap-fit, etc.) the holes 1.10 to secure the sections 1.1.1 in the closed position. 5 The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by opening the sections 1.1.1 about the hinge and placing the syringe 2 in the syringe carrier 2. When the sections 1.1.1 are closed, the pins 1.11 engage the holes 1.10, and the proximal shoulder sections 1.4 form circular shoulders adapted to 0 proximally abut a finger flange 2.3 on the syringe 2 and the distal shoulder section s1.4 to distally engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1. In an exemplary embodiment, the proximal end 1.5 may include a retainer element 1.7 5 which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D. In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 20 and distally-facing planar surfaces to abut the RNS 4. In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut 25 outs in the sections 1.1.1 are substantially contiguous when the sections 1.1.1 are in the closed position. A projection 1.6 may be formed around each cut-out, and when the sections 1.1.1 are in the non-deflected position, the projections 1.6 may form an outline for the window 5. 30 Figures 14-18 show a fourth exemplary embodiment of a syringe carrier 1 according to the present invention. Figure 14 is a top view of a fourth embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 15 is a lateral view of the syringe carrier 1 of WO 2013/083614 PCT/EP2012/074468 12 figure 14. Figure 16 is a longitudinal section of the syringe carrier 1 of figure 14 in the section plane A-A. Figure 17 is a perspective view of the syringe carrier of figure 14 without the syringe 2. Figure 18 is another perspective view of the syringe carrier of figure 14. 5 As shown in Figures 14-18, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 has a cylindrical shape with an internal diameter corresponding to the diameter of the barrel 2.1. A distal end of the body 1.1 includes a shoulder sections 1.4 shaped as a portion 0 of a circle arranged in a transverse plane with respect to a longitudinal axis of the carrier 1, and at least one door 1.12 hingedly coupled to the body 1.1 and including a shoulder section 1.4. A hinge 1.9 coupling the door 1.12 to the body 1.1 may be provided on an axis parallel to the longitudinal axis of the syringe carrier 1 or on an axis transverse to the longitudinal axis of the syringe carrier 1. The shoulder section 1.4 includes facing 5 surfaces 6 which abut facing surfaces 6 of the door 1.12 when the door 1.12 is in a closed position (as shown in Figure 14). When the door 1.12 is in the closed position, the facing surfaces 6 may abut each other so that the shoulder sections 1.4 on the body 1.1 and the door 1.12 to form a circular shoulder adapted to engage the circumferential gap between the barrel 2.1 and the RNS 4. The facing surfaces 6 of the door 1.12 may 20 include holes 1.10 and the facing surfaces 6 of the body 1.1 may include pins 1.11 (or vice-versa) adapted to engage (e.g., frictionally, snap-fit, etc.) the holes 1.10 to secure the door 1.12 in the closed position. The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe 25 carrier 1 by opening the door 1.12 and sliding the syringe 2 into the syringe carrier 1. When the circumferential gap between the barrel 2.1 and the RNS 4 engages the shoulder section 1.4 on the body 1.1, the door 1.12 may be closed to engage the gap and prevent the syringe 2 from moving axially relative to the syringe carrier 1. 30 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.

WO 2013/083614 PCT/EP2012/074468 13 In an exemplary embodiment, viewing windows (not shown) may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows are formed as 5 cut-outs. Figures 19-23 show a fifth exemplary embodiment of a syringe carrier 1 according to the present invention. Figure 19 is a top view of a fifth embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 20 is a lateral view of the syringe carrier 1 of figure 19. 0 Figure 21 is a longitudinal section of the syringe carrier 1 of figure 19 in the section plane A-A. Figure 22 is a perspective view of the syringe carrier of figure 19 without the syringe 2. Figure 23 is another perspective view of the syringe carrier of figure 19. As shown in Figures 19-23, the syringe carrier 1 comprises an elongate body 1.1 5 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 is comprised of two sections 1.1.1 which, when together, have a cylindrical shape with an internal diameter corresponding to the diameter of the barrel 2.1. The sections 1.1.1 may be coupled together by clips. In an exemplary embodiment, a clip may comprise a eye 1.14 on a first section adapted to engage a hook 1.13 on a second section. The 20 eye 1.14 may have a cross-section substantially equal to the cross-section of the hook 1.13 such that the eye 1.14 and hook 1.13 engage in a snap-fit. Distal ends of the sections 1.1.1 include shoulder sections 1.4 shaped as portions of a circle arranged in a transverse plane with respect to a longitudinal axis of the carrier 1. The shoulder sections include facing surfaces 6. When the sections 1.1.1 are in a closed position, the 25 facing surfaces 6 may abut each other so that the shoulder sections 1.4 form circular shoulders adapted engage the circumferential gap between the barrel 2.1 and the RNS 4. Those of skill in the art will understand that the sections 1.1.1 may be hingedly connected. 30 The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by opening the sections 1.1.1 and placing the syringe 2 in the syringe carrier 2. When the sections 1.1.1 are closed, the eyes 1.14 engage the hooks 1.13 and the WO 2013/083614 PCT/EP2012/074468 14 shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1. 5 In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.

In an exemplary embodiment, viewing windows may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the 5 syringe carrier 2. Figures 24-28 show a sixth exemplary embodiment of a syringe carrier 1 according to the present invention. Figure 24 is a top view of a sixth embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 25 is a lateral view of the syringe carrier 1 of figure 20 24. Figure 26 is a longitudinal section of the syringe carrier 1 of figure 24 in the section plane A-A. Figure 27 is a perspective view of the syringe carrier of figure 24 without the syringe 2. Figure 28 is another perspective view of the syringe carrier of figure 24. As shown in Figures 24-28, the syringe carrier 1 comprises an elongate body 1.1 25 arranged to receive the barrel 2.1.

The shoulder sections 14 form circular shoulders adapted to engage the circumferential gap between the barrel 2.1 and the RNS 4. The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe 5 carrier 1 by pressing the barrel 2.1 against the clamps 1.15, 1.16, causing the clamps 1.15, 1.16 to deflect and widen the longitudinal slot in the body 1.1. When the barrel 2.1 bypasses the clamps 1.15, 1.16, the clamps 1.15, 1.16 return to their non-deflected position and retain the syringe 2 in the syringe carrier 1. The shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the 0 syringe 2 is prevented from moving axially relative to the syringe carrier 1. In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D. 5 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. 20 In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.

In this exemplary embodiment, the body 1.1 has a partially cylindrical shape with an internal diameter corresponding to the diameter of the barrel 2.1. The body 1.1 includes a collar 1.2 at its proximal end and may include a 5 longitudinal slot (e.g., a cut-out) formed in the body 1.1 distally of the collar 1.2 which is adapted to snap over the barrel 2.1 of the syringe 2. A pair of groove hinges 1.17 may be formed in the body 1.1 adjacent a proximal end of the slot. The distal end of the body 1 includes shoulder sections 1.4 shaped as a portion of a circle arranged in a transverse plane with respect to a longitudinal axis of the carrier 1. The shoulder 0 sections 14 form circular shoulders adapted to engage the circumferential gap between the barrel 2.1 and the RNS 4. The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 through the collar 1.2 in the distal direction D. When 5 the RNS 4 abuts the shoulder sections 1.4, the body 1.1 may radially deflect (e.g., rotate) about the groove hinges 1.17. When the RNS 4 bypasses the shoulder sections 1.4, the body 1.1 may return to its non-deflected position and retain the syringe 2 in the syringe carrier 1. The shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially 20 relative to the syringe carrier 1. In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D. 25 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. 30 In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.

Figure 34 is a top view of an eighth embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 35 is a lateral view of the syringe carrier 1 of 5 figure 34. Figure 36 is a longitudinal section of the syringe carrier 1 of figure 34 in the section plane A-A. Figure 37 is a perspective view of the syringe carrier of figure 34 without the syringe 2. Figure 38 is another perspective view of the syringe carrier of figure 34. 0 As shown in Figures 34-38, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 has a cylindrical shape with an annular groove 1.19 adjacent its distal end which is adapted to engage a circlip 8. The circlip 8 may engage the circumferential gap between the barrel 1.2 and the RNS 4. 5 The syringe 2, with RNS 4 attached to the needle 3 and the circlip 8 attached to the syringe 2, may be loaded into the syringe carrier 1 by sliding the syringe 2 into the syringe carrier 1 in the distal direction D. In a non-deflected position, an outer diameter of the circlip 8 may be substantially equal to a diameter of the body 1.1. Thus, when the 20 syringe 2 with the circlip 8 is inserted into the syringe carrier 1, the circlip 8 may deflect radially until the circlip 8 reaches the annular groove 1.19. The circlip 8 may then expand to the non-deflected position and retain the syringe 2 in an axial position relative to the syringe carrier 1. That is, the circlip 8 may engage the annular groove 1.19 and the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is 25 prevented from moving axially relative to the syringe carrier 1. In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D. 30 WO 2013/083614 PCT/EP2012/074468 18 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. 5 In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. Figures 39-43 show a ninth exemplary embodiment of a syringe carrier 1 according to 0 the present invention. Figure 39 is a top view of a ninth embodiment of a syringe carrier 1 for supporting a syringe 2. Figure 40 is a lateral view of the syringe carrier 1 of figure 39. Figure 41 is a longitudinal section of the syringe carrier 1 of figure 39 in the section plane A-A. Figure 42 is a perspective view of the syringe carrier of figure 39 without the syringe 2. Figure 43 is another perspective view of the syringe carrier of figure 39. 5 As shown in Figures 39-43, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 has a cylindrical shape with an annular groove 1.19 having at least one aperture 1.20 adjacent its distal end which is adapted to engage a circlip 8. 20 The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 into the syringe carrier 1 in the distal direction D. When the circumferential gap between the barrel 2.1 and the RNS 4 is aligned with the annular groove 1.19, the circlip 8 may be coupled to the body 1.1 and engage the 25 apertures 1.20. By extending inwardly through the apertures, the circlip 8 may be coupled to the outside of the body 1.1 but engage the circumferential gap between the barrel 2.1 and the RNS 4. The engagement between the circlip 8 and the apertures 1.20 prevents the circlip 8 from translating relative to the body 1.1, and the engagement between the circlip 8 and the circumferential gap prevents the syringe 2 from moving 30 axially relative to the syringe carrier 1.

WO 2013/083614 PCT/EP2012/074468 19 In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D. 5 In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4. In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for 0 allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. Figures 44-48 show a tenth exemplary embodiment of a syringe carrier 1 and a tool 9 for inserting a syringe 2 into the syringe carrier 1 according to the present invention. 5 As shown in Figures 39-43, the syringe carrier 1 comprises an elongate body 1.1 arranged to receive the barrel 2.1. In this exemplary embodiment, the body 1.1 has an enlarged portion 1.21 on its distal end.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe 25 carrier 1 by inserting the tool 9 into the enlarged portion 1.21 of the syringe carrier 1. The tool 9 may be a cylinder having an open end adapted to receive the RNS 4. The tool 9 may have a third diameter substantially equal to the second diameter. As the tool 9 is inserted into the enlarged portion 1.21, the tool 9 engages and deflects the resilient barbs 1.22. When the barbs 1.22 are deflected, the RNS 4 can pass the barbs 1.22 in 30 the distal direction D and extend from a distal opening of the body 1.1. When a finger flange 2.3 of the syringe 2 abuts a proximal end of the body 1.1, the tool 9 may be removed and the barbs 1.22 may engage the circumferential gap between the barrel 2.1 WO 2013/083614 PCT/EP2012/074468 20 and the RNS 4 to prevent the syringe 2 from moving axially relative to the syringe carrier 1.
